I also updated one of my PCs to 22H2 and discovered the registry mod to place the taskbar on top no longer works. I reverted back to the previous version 21H2, build 22000.1098. For me the touted new features were not worth losing the Taskbar on top.
I found that after the return to version 21H2, build 22000.1098, MS Edge no longer launches. I did all the Windows recommended fixes, but it is still MIA. Edge snaps open perfectly on another similar PC that I did not update to 22H2.
